Turing Complete Mechanical Computer (Z1, Z2, Z3, Z4)The Z-series computers are notable as the first recognized as the first “Turing complete” (modern) computer. The Nazis did not see the computer as strategically important and invested little in it. The company survived the war but there was little demand for their machines. They eventually sold the patents to the Americans. Zuse worked for … Continue reading "Turing Complete Mechanical Computer (Z1, Z2, Z3, Z4)"
Optical Character Recognition (OCR)Optical Character Recognition (OCR) technology increases productivity and decreases cost by alleviating the need for humans to type printed information into computers. It also reduces the risk of typos. David Shepherd’s OCR machine was used in few places. Most notably, Reader’s Digest used it to manage subscription information, transforming printed material to punch cards. Other … Continue reading "Optical Character Recognition (OCR)"
Cathode-ray Tube (CRT)Cathode ray tubes are a vacuum tube with an electron gun at the back. The gun shoots electrons through the vacuum onto a screen which creates images. Thick screens that predate flat-screen televisions and computer monitors are cathode ray technology. Background German scientists Julius Plücker and Johan Hittorf discovered cathode-ray tubes. Hittorf noticed a negative … Continue reading "Cathode-ray Tube (CRT)"
Suez CanalThe Suez Canal connects the Arabian and Red Sea to the Mediterranean. The canal is one of the two most important human-engineered waterways in the world. Background Think your remodel took a long time? Or your software project went horribly over time and budget? Maybe a movie took too long to make? North Korea has … Continue reading "Suez Canal"
Time-Sharing/Multitasking ComputerEarly Computers Early computers stored programs and data on punch cards. Most cards contained 80-characters, which is why early terminal programs were typically 80-characters per line. Punch cards are exactly what they sound like, physical cards. Each card is one line of a computer program or one piece of data. As users typed, a machine … Continue reading "Time-Sharing/Multitasking Computer"
X-Ray ImagingIn 1895, Wilhelm Röntgen noticed that electromagnetic radiation would expose bone structure under certain conditions. He invented the medical X-Ray machine. For his invention, Röntgen received the first Nobel Prize for Physics, in 1901, and several other illustrious awards. Due to WWI, companies were forbidden from paying the German royalties and his savings were destroyed … Continue reading "X-Ray Imaging"
Windshield WiperWindshield wipers are a vital component of a car. Inclusion Criteria However, countless other components in cars are also important. Excluding the vast majority of auto components from innowiki is a purposeful decision. Undoubtedly, these components are oftentimes enormous markets. However, they do not teach us about anything especially important. They are components in a … Continue reading "Windshield Wiper"
Color MoviesThough not the first color movie, The Wizard of Oz left an indelible mark. Swapping from the old world of black and white to color the world flew over the rainbow. Movies have never been the same since. Kalmus, an MIT alum, created a process for color movies and ramped up a company, Technicolor. Initially, … Continue reading "Color Movies"
Console Gaming SystemsConsole game systems are specialized computers that play games. Ralph Baer came up with the idea of a video-game system that connects to televisions in 1966. Magnavox agreed to manufacture and distribute his seventh prototype, in 1971, branded the Odyssey. Magnavox sold about 350,000 units, at the then steep price of $100, before discontinuing it … Continue reading "Console Gaming Systems"
StatinsStatins dramatically lower blood cholesterol, and the likelihood of heart attacks. Akira Endo discovered statins. Akira Endo & His Molds Endo is a Japanese researcher with a lifelong fascination related to fungi. Recalling that Fleming accidentally discovered penicillin, he theorized that fungi might hold other miracle drugs. Endo noted that Americans are much heavier than … Continue reading "Statins"
Breach Loaded FirearmsFlintlock guns required the user to pour gunpowder into the barrel of the weapon, stamp it down, add a bullet, then carefully pick the whole thing up and fire it. By the time all that finished, soldiers could be chased down and stabbed with a knife. Breach-loading firearms opened the rifle near the back. They … Continue reading "Breach Loaded Firearms"
Gas Extraction from Coal & Gas Powered LanternCombining gas extracted from coal into a lantern, then into lights, allowed for non-candle bright lights. This literally lit up the industrial era. Factories could function at night and people could stay awake longer. Gas lighting vastly increased productivity. In 1667, Thomas Shirley published a report describing flammable gas naturally seeping from coal. In 1684, … Continue reading "Gas Extraction from Coal & Gas Powered Lantern"
Magnetic Tape RecordingPoulsen, a Danish engineer, created and patented a machine that recorded onto magnetic tape. His called the invention a Telegraphone. There was no amplification and the recording quality was poor. In 1928, Pfleumer, a German, vastly improved the magnetic tape. He named his device a Magnetophone. During WWII the Germans used it for communications and … Continue reading "Magnetic Tape Recording"
Vaccines (Smallpox)Smallpox was a killer, affecting royalty and peasants alike. When it didn’t kill, it oftentimes left victims permanently maimed. Besides eventually eradicating smallpox, this vaccine led to the development of future ones. Background Jenner was born to a wealthy and well-educated family. Like many during his time, he was inoculated for smallpox, a process where … Continue reading "Vaccines (Smallpox)"
Electrical Transformer1831 Michael Faraday Faraday’s transformer acted as a knowledge bridge to future innovators that electricity could be transformed. It wasn’t especially useful on its own except to signal to future scientists what is possible. His transformer was vital to the creation of the modern electricity grid and electrical innovations. The device itself is hand-built by … Continue reading "Electrical Transformer"
